Very easy and convenient. FilterBuy even had filter sizes for my furnace unit that I couldn’t find anywhere else. Prices are comparable to what I’d pay for the same filter at the store. With free shipping at my own custom interval, this is really unbeatable. I highly recommend for any homeowner.

Build a Custom Size

Simply measure the length and width of your filter with a tape measure and choose the closest size
(to 1/8”) in the drop down menu. 1/8” tolerance is standard and should not cause a problem in any
standard filter application.

Please note that the ‘actual’ filter size, ie the size that your tape measure shows, should be used when
creating a filter with this tool, not a nominal filter size. Note that the depths of each filter are
standard, as shown to the right.
